The (E)AC-3 AVParser should split the (E)AC-3 stream so that the chunks of data send to the decoder (ac3_decode_frame) are complete and contain all channels. So ac3_decode_frame() would receive as input several "ac3 frames" if some channels are stored in future frames.
Hi, Recently I had some free time, so I've tried to work on the parser. I encountered one problem: ff_aac_ac3_parse function in aac_ac3_parser.c needs to know stream_type. As an interface to read data about the stream it uses
What stream_type ? I dont understand you. ac3_sync() could just return the sum of the len of both frames (so all channels are available) or am i missing something?
No, it isn't that simple: ac3_sync is given a buffer, which has only header_size bytes. So it isn't able to read headers of following frames and it doesn't know if they're an extension of current frame.... -- Bartlomiej Wolowiec
